Mr. Seidel started his martial arts journey in the fall of 1978 at Kim's Karate School in Omaha, Nebraska, where Mr. Seidel grew up. Training 5 days a week, Mr. Seidel earned the rank of purple belt when he started college at Southern Methodist University in the fall of 1980. In those early days, the ranking system had only the following colors: white, yellow, green, purple, brown, and black. The Kim's Karate School curriculum was traditional and conservative. We only wore shin and instep pads – no hand, head, or chest protection. Our target area in sparring was from the belt to the shoulders – no head contact.

Mr. Seidel was promoted to first-degree black belt in 1982 at a tournament and testing under Master Kim in Kansas City, KS. The World Taekwondo Association, of which Kim’s Karate was a member, traditionally promoted its brown belts to black in a regional tournament and testing, during which all the senior black belts were in attendance.

From 1980 to 1987, while at SMU and after, Mr. Seidel learned 'Texas-style' Taekwondo. The distinguishing factor of this system was that 1) groin and head contact was permitted, 2) all fighters wore hand protection (but not headgear), and 3) at brown and black belt levels, sparring was expected to be 'full contact.' Mr. Seidel studied under martial arts grandmasters like Keith Yates, Bob Woerner, Michael Proctor, Paul Hinkley, and many others, and even today, Mr. Seidel still incorporates the lessons of that time frame.

In 1987, Mr. Seidel moved to the Washington, DC, area. He started training under Masters Neil Ehrlich and Danny Bocagno at the American Karate Institute, where the focus was on kickboxing. This training honed Mr. Seidel's handwork, which seems to be partially lost in modern Taekwondo. Mr. Seidel was promoted to 2nd Dan in 1991.

From 1991 until 1998, Mr. Seidel practiced intermittently as he had a new construction company and two small children. In 1998, Mr. Seidel's son was taking Taekwondo from the Black Belt Academy in Fairfax. Mr. Seidel then joined that teaching team and taught an advanced-belt, invitation-only adults class and coached a sparring team.

In 2011, Mr. Seidel started training and teaching at the Tiger Claw Taekwondo Studio in Leesburg, VA, and in 2014 tested and was awarded a 3rd Dan black belt in Taekwondo.

In about 2000, Mr. Seidel studied Aikido for three years until his sensei moved away. He earned the rank of blue belt in this art.

In 2005, Mr. Seidel began studying Combat Hapkido, which offered classes only 2-3 days per week. 2012, Mr. Seidel tested and was awarded a 1st Dan black belt. Mr. Seidel continued to train in the art and tested and was awarded a 2nd Dan black belt in 2014.

In 2015, Mr. Seidel felt the Lord leading him to start teaching "in an area where they needed him ." This was the beginning of the Movement Martial Arts, and we started in a community center in Northeast DC. And it was early in the Movement that Pastor Welton Bonner (now PhD) and his good friend Phillip Ford showed up. These two life-long friends and spiritual brothers had taken martial arts classes when they were younger. The Movement of Martial Arts allowed them to start learning again. The collaboration of the three birthed the conceptual framework for The Movement of Martial Arts and Fitness.

In 2016, Mr. Seidel was awarded a 4th Dan Black belt in Taekwondo and a 5th Dan Black belt in 2024.
